How wearables are impacting research
As an organization that develops research solutions built around the capabilities of wearable devices, we often find ourselves in awe of what’s coming right around the corner. This article documents via statistics and collection of facts just how important these devices are in the realm of medicine as well as health research.
Relentless and Accelerating Adoption Growth
The honor of the very first wearable of the modern era can be argued to no end, but one candidate that has a strong case is the HP-01 multi-function watch launched in 1977. It featured such fancy technologies as Time of Day, Calendar, Alarm and most impressively at the time a calculator. The fact that the watch was sold in jewelry stores and was priced more than a Rolex might have contributed to poor adoption overall sales numbers. Fast forward to today and we have countless super intelligent wearables on the market with sales totaling in the millions.
Here are some highlights:
- 533.6 million - total wearable devices shipped in 2021, this number includes hearables, watches, wrist-bands, and other wearables. (source: statista.com)
- 253 million - smartwatch shipments worldwide are forecast to grow to over 253 million units by 2025. (source: statista.com)
- 31 million active Fitbit users - In 2020, there were 31 million active users of Fitbit products who used their device at least once a week. (source: statista.com)
- 18 million active Garmin users - As reported in the Guardian article from January of 2020, there were at the time approximately 18 million Garmin watch users. (source: Strategy Analytics)
- 30% of Americans use wearable health devices - This is according to a survey conducted by the Journal of Internet Medical Research. (source: NIH.gov)
